Telkom At it again

My current contract ends in April. I was called to ask if I wanted to upgrade. I said yes and the router etc has arrived. However I see the product comes from Sell Direct Marketing and I can't contact them on the number. I need clarification if I am going to have a contract overlap and have to pay for both or when will the one end and new begin. I have tried twitter but they just ask for an ID number instead of reading the request and responding. How do I get someone to respond. Have emailed with explanation of my request and get the response "Thank you for email, Kindly be advised that turnaround time is 24 to 48 working hours." Turnaround time for what??? Please guys earn your salaries and read the questions and answer them directly!!
